Peculiarities of spin reorientation in a thinYIG lm

چکیده
The issue of magnetic orientation transitions in thin lms combines interesting physics and importance for applications. We study the magnetic transition and phase diagram of a 0.1 m thick (YLaGd)3(FeGa)5O12 lms grown on GGG substrate by liquid phase epitaxy. Observed transitions are compared with those in BiGa:TmIG thin lms, studied in previous work by one of the authors. A general picture of orientation transitions in thin lms of substituted YIG is discussed.

Characterization of the Reorientation Transition in Classical Heisenberg Models with Dipole Interaction
In this paper the thermodynamics of thin ferromagnetic lms are studied in the framework of the classical Heisenberg model with uniaxial anisotropy and long{range dipole interaction. The dependence of the order of the reorientation transition in these systems on the number of layers and on the distribution of anisotropies is investigated using both mean eld theory and Monte{Carlo simulations. Th...
متن کاملSpin-reorientation magnetic transitions in Mn-doped SmFeO3
Spin reorientation is a magnetic phase transition in which rotation of the magnetization vector with respect to the crystallographic axes occurs upon a change in the temperature or magnetic field. For example, SmFeO3 shows a magnetization rotation from the c axis above 480 K to the a axis below 450 K, known as the Γ4 → Γ2 transition. This work reports the successful synthesis of the new single-...
متن کاملSPIN REORIENTATION PHENOMENA IN SUBSTITUTED Pr2 (Co, Fe)17 INTERMETALLICS
The magnetic anisotropy phase diagrams of Pr2Co17-,Fen and Pr2Co17-,Fez-,Ty (T=Mn, Zr, Ti, Hf) compounds have been determined. Two spin reorientation temperatures, TSr1 and Tsr2, have been observed. Near the Ts,l or Ts,2 boundary the anisotropy is conical; between the two spin reorientation temperatures they exhibit uniaxial anisotropy and beyond these limits they are planar. Introduction --0-y...
متن کاملTerahertz probes of magnetic field induced spin reorientation in YFeO 3 single crystal
Using the terahertz time-domain spectroscopy, we demonstrate the spin reorientation of a canted antiferromagnetic YFeO3 single crystal, by evaluating the temperature and magnetic field dependence of resonant frequency and amplitude for the quasi-ferromagnetic (FM) and quasi-antiferromagnetic modes (AFM), a deeper insight into the dynamics of spin reorientation in rare-earth orthoferrites is est...
متن کاملStudy of spin-ordering and spin-reorientation transitions in hexagonal manganites through Raman spectroscopy
Spin-wave (magnon) scattering, when clearly observed by Raman spectroscopy, can be simple and powerful for studying magnetic phase transitions. In this paper, we present how to observe magnon scattering clearly by Raman spectroscopy, then apply the Raman method to study spin-ordering and spin-reorientation transitions of hexagonal manganite single crystal and thin films and compare directly wit...
